Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of strength detection, in particular to a titanium plate strength detection device. BACKGROUND

[0002] Titanium plate strength detection, as a key technical link for evaluating material mechanical properties and ensuring the safety of engineering applications, is mainly divided into three categories: static strength detection, dynamic fatigue strength detection and environmental adaptability strength detection. During the detection process, standard samples with specific geometric shapes need to be prepared according to different detection project requirements, rather than directly testing the original titanium plate product.

[0003] For titanium plate compressive strength detection, the core principle is to apply axial pressure through a special loading device to evaluate the material's ability to resist plastic deformation or crushing failure. To prevent the sample from buckling instability due to excessive slenderness ratio during compression, the sample must be designed in a short and thick shape, mainly using cylindrical and square column shapes.

[0004] The standard detection process requires the operator to first clean the two end faces of the sample precisely, then evenly apply special lubricant to reduce the friction coefficient between the end face and the pressure head, avoiding stress distribution distortion caused by friction effects. After the lubricant is applied, the sample needs to be accurately placed in the center of the lower compression table, and the sample is precisely positioned through the pre-compression operation of the upper compression table, and then the formal compressive strength detection is carried out.

[0005] However, the traditional manual application method not only has a complicated operation process and low efficiency, but more importantly, it is difficult to ensure uniform distribution of the lubricant on the sample end face, which is prone to form local over-thick or over-thin areas. This uneven application will directly affect the positioning accuracy and stability of the sample on the compression table, causing the sample to be eccentric or inclined during the pre-compression stage, and then the upper and lower pressure heads cannot achieve coaxial clamping of the sample, resulting in uneven stress distribution during loading, generating additional bending moment, and ultimately leading to systematic deviation of the detection data, seriously affecting the accuracy and reliability of the detection results.

[0023] In actual application, the embodiments of the present application are as follows: Figure 2 and Figure 3As shown, first, the titanium plate sample is placed in the positioning mechanism 65 to achieve auxiliary positioning and preliminary clamping of the titanium plate sample. The movable end of the electric guide rail 61 drives the movable block 62 to move along the guide rail direction. Then, the mounting seat 64 and the positioning mechanism 65 are driven to move downward as a whole through the movable frame 63. During the downward movement of the mounting seat 64, the movable frame 71, the fixed frame 72, and the cleaning mechanism 73 are simultaneously driven to move downward by the support mechanism 74. When the cleaning assembly 7 moves downward with the mounting seat 64 to contact the surface of the lower pressure bearing table 5, the lower pressure bearing table 5 generates an upward supporting force on the cleaning assembly 7. Under the action of the supporting force, the movable frame 71 slides upward relative to the fixed frame 72, which drives the cleaning mechanism 73 to slide along the fixed frame 72 through the transmission structure therebetween. The cleaning mechanism 73 simultaneously cleans and lubricates the surface of the lower pressure bearing table 5 and the bottom surface of the titanium plate sample during the sliding process. At the same time, the movable seat 3 moves downward along the internal slide rail of the support 2 under the action of the existing external driving force, which simultaneously drives the upper pressure head 4 to move downward. The pressure ring 82 connected to the bottom of the movable seat 3 through the fixed rod 81 moves downward with the movable seat 3. When the pressure ring 82 contacts the top cleaning assembly 7, it generates a downward extrusion force on the top cleaning assembly 7. Under the action of the extrusion force, the movable frame 71 in the top cleaning assembly 7 slides downward relative to the fixed frame 72. The top cleaning mechanism 73 is driven to slide through the internal transmission structure, which cleans and lubricates the top surface of the titanium plate sample and the bottom surface of the upper pressure head 4. As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 , after the above cleaning and lubricating process is completed, the electric push rod 66 is started, and its movable end pushes the mounting seat 64 to move along the internal slide rail of the movable frame 63, which in turn drives the positioning mechanism 65 to release the clamping state of the titanium plate sample. At this time, the movable seat 3 continues to drive the upper pressure head 4 to move downward, which applies an axial pressure to the titanium plate sample through the cooperation of the upper pressure head 4 and the lower pressure bearing table 5, thereby completing the compression strength detection process. This realizes the automation of titanium plate sample clamping, cleaning and lubrication, and strength detection, effectively improving the detection efficiency and accuracy.

[0024] As shown in Figure 3 , Figure 4 and Figure 5 , the positioning mechanism 65 includes a support frame 651 and a connecting block 653. The support frame 651 is fixedly connected to the mounting seat 64 through the connecting block 653. Two positioning rods 652 are slidably connected inside the support frame 651. A spring 654 is fixedly connected between one end of the positioning rod 652 and the support frame 651. A positioning block 655 is fixedly connected to the other end of the support frame 651.

[0025] The positioning mechanism 65 is rigidly connected with the mounting seat 64 through the connecting block 653 in actual application of the embodiment of the application, overall synchronous movement is realized, when the titanium plate sample is placed into the support frame 651, the sample side surface is in contact with the positioning block 655 and extrusion is generated, the positioning block 655 transmits the force to the positioning rod 652, the positioning rod 652 slides along the guide hole of the support frame 651, and the spring one 654 is stretched at the same time; The spring one 654 stores elastic potential energy in the stretching process, the reaction force of the spring one 654 acts on the titanium plate sample side surface through the positioning rod 652 and the positioning block 655, clamping force is formed, the sample is ensured to be centrally positioned in the support frame 651, transverse deviation is effectively prevented, the whole positioning process realizes self-adaptive clamping by using the elastic characteristics of the spring one 654, titanium plate samples of different thickness specifications can be compatible, and the positioning precision is ensured by the rigid structure of the support frame 651.

[0026] As shown in Figure 3 , Figure 10 , Figure 11 and Figure 12 , the cleaning mechanism 73 includes a cleaning seat 731 and a guide seat 732, the spring two 734 is fixedly connected between the cleaning seat 731 and the guide seat 732, the guide rod 733 is fixedly connected to the end, away from the cleaning seat 731, of the guide seat 732, the two guide rubber strips 737 are fixedly connected to the outside of the cleaning seat 731, the smearing strip 736 is fixedly connected between the two guide rubber strips 737, the inclined slot is formed in the outside of the movable frame 71, the guide rod 733 is slidingly installed in the inclined slot on the movable frame 71, the horizontal slot is formed in the outside of the fixed frame 72, the guide seat 732 is slidingly installed in the horizontal slot on the fixed frame 72, the limiting shaft 735 is fixedly connected to the outside of the cleaning seat 731 in a symmetrical mode, and the limiting shaft 735 is slidingly connected to the inside of the guide seat 732.

[0027] In actual application of the embodiment of the application, when the movable frame 71 and the fixed frame 72 move relatively, the inclined slot on the outside of the movable frame 71 generates a transverse thrust on the guide seat 732 through the guide rod 733, the guide seat 732 can only slide in the horizontal direction because the guide seat 732 is limited by the horizontal slot on the outside of the fixed frame 72, therefore the guide seat 732 drives the cleaning seat 731 to move transversely synchronously; During the movement of the cleaning seat 731, the guide rubber strips 737 on the outside of the cleaning seat 731 first contact the surface to be cleaned, prepositioning and preliminary cleaning are realized through flexible deformation, then the smearing strip 736 contacts the surface, the smearing strip 736 is ensured to be closely attached to the surface under the elastic pressure of the spring two 734, uniform oil smearing is realized, the limiting shaft 735 slides in the inside of the guide seat 732, and the movement of the cleaning seat 731 is guided and deviation of the cleaning seat 731 is prevented.

[0028] As shown in Figure 3 , Figure 5 , Figure 6 ,Figure 7 and Figure 8 As shown in

[0029] When the height of the supporting mechanism 74 needs to be adjusted, the operator presses the sliding rod 757 to make it slide axially along the rotating rod 751, which drives the positioning disc 755 to move synchronously, compresses the spring four 756, and makes the positioning disc 755 disengage from the gear 754 to release the braking effect on the gear 754. At this time, the rotating rod 751 is rotated, and the gear 754 inside the rotating rod 751 rotates accordingly. Since the gear 754 is engaged with the two symmetrically arranged racks 752, the rotational motion of the gear 754 is converted into the linear motion of the racks 752. The two racks 752 slide reversely inside the rotating rod 751, and through the fixed sliding block 753 at the end, the height of the supporting mechanism 74 is adjusted. When the supporting mechanism 74 is adjusted to the required height, the sliding rod 757 is loosened. Under the elastic force of the spring four 756, the positioning disc 755 resets and reattaches to the gear 754. Through the friction torque between the positioning disc 755 and the gear 754, the gear 754 is locked, thereby fixing the positions of the racks 752 and the sliding block 753, ensuring that the height of the supporting mechanism 74 remains stable to adapt to the detection requirements of titanium plate samples of different lengths.

[0030] As shown in Figure 3 、 Figure 9 and Figure 10 The supporting mechanism 74 includes two fixed blocks 742 symmetrically fixed to the outer side of the movable frame 71. The outer side of the fixed frame 72 is symmetrically fixed with two supporting seats 741. The supporting seat 741 and the fixed block 742 are fixedly connected with the spring three 743. The supporting seat 741 is slidingly connected with the sliding block 753. The outer side of the supporting seat 741 is fixedly connected with the limiting rod 744. The fixed block 742 is slidingly connected to the outer side of the limiting rod 744. The spring three 743 is sleeved on the outer side of the limiting rod 744.

[0031] In actual application, the support mechanism 74 adjusts the height by the sliding cooperation of the support seat 741 and the sliding block 753, when the adjusting mechanism 75 drives the sliding block 753 to move in the vertical direction, the support seat 741 is lifted and lowered synchronously with the sliding block 753, thereby driving the fixed frame 72 and the whole cleaning assembly 7 to adjust to the working position adapting to the length of the titanium plate sample; During the cleaning operation, when the movable frame 71 and the fixed frame 72 move relative to each other, the fixed block 742 slides along the axis direction of the limiting rod 744, the spring three 743 is elastically deformed correspondingly, the elastic force of the spring three 743 acts on the movable frame 71 through the fixed block 742, thereby providing the cleaning mechanism 73 with continuous contact pressure, ensuring that the guiding rubber strip 737 and the smearing strip 736 are tightly attached to the cleaned surface; The limiting rod 744 not only limits the movement track of the fixed block 742, preventing it from deviating or being stuck, but also plays a guiding role on the spring three 743, avoiding the spring from being laterally bent or twisted during the expansion and contraction, thereby ensuring the reliability and uniformity of the cleaning and oiling operation.
